Glow-worm Ultimate3 System Fault codes & diagnostics

Your boiler has stopped working because it can no longer accurately measure the temperature of the water circulating inside it.

Your boiler has stopped working because it is unable to accurately measure the temperature of the water returning to it from your radiators.

Your boiler has stopped working because it is unable to accurately measure the temperature of the water inside the system due to a faulty electrical connection or sensor.

Your boiler has detected an electrical fault with one of its internal temperature sensors, causing it to stop operating as a safety precaution.

Your boiler has detected that it is running too hot and has automatically shut itself down to prevent damage.

Your boiler has stopped working because the water pressure inside the system has dropped too low.

Your boiler has detected that the water inside is heating up too irregularly, so it has safely shut itself down to prevent damage to internal parts.

Your boiler has detected that the water inside is heating up far too quickly, which has triggered a safety shutdown to prevent damage.

Your boiler has detected that the gases it is producing are too hot and has automatically shut down to prevent internal damage.

Your boiler has detected an issue with its flame sensor and has safely shut down because it cannot confirm if the burner is lit correctly.

Your boiler is failing to light the burner, meaning it cannot produce heating or hot water.

Your boiler is struggling to keep its internal flame lit while trying to heat your home.

Your boiler has detected that the internal fan is spinning at the wrong speed, possibly because it is struggling to operate in very cold conditions.

Your boiler is having trouble communicating with its electronic control system because the electrical signal between them is too weak.

Your boiler has detected a problem with the internal part that controls the flow of gas, meaning it is currently unable to ignite properly.

Your boiler's computer has detected a memory error and can no longer process its operating instructions correctly.

Your boiler has detected an internal communication error with its main control board or sensors, which will prevent your heating and hot water from working.

The main control board inside your boiler is overheating and has shut the system down to prevent permanent damage.

Your boiler has detected an internal electronic error while trying to monitor the flame, meaning it cannot safely operate and has shut down to protect itself.

Your boiler is struggling to keep the flame steady, causing it to shut down for safety reasons.

Your boiler’s internal computer has forgotten its identity, meaning it doesn't know how to operate correctly because its configuration data has been lost or corrupted.

Your boiler is currently unable to read the water temperatures correctly, so it has shut down as a precaution to prevent damage.

Your boiler has detected a disagreement between its internal pressure and temperature sensors, causing it to block its own operation to prevent potential damage.

Your boiler is unable to read the water pressure level because the sensor responsible for checking it has lost its connection or has stopped working correctly.

Your boiler's sensor is having trouble reading the water pressure, so it has shut down to prevent potential damage.

Your boiler is failing to detect the water pressure correctly, which prevents it from firing up safely.

Your boiler has detected an issue with the drainage of waste water created during the heating process, which may cause it to shut down to prevent internal damage.

Your boiler has detected that there is either no water or insufficient water circulating inside it, causing the system to shut down to prevent damage.

Your boiler has detected that the sensors measuring the temperature of the water flowing in and out of the system are providing inconsistent or conflicting information, causing it to shut down to prevent damage.

Your boiler has detected that a temperature sensor is not reading correctly, so it has stopped working to prevent potential overheating.

Your boiler is failing to light the flame because the ignition system cannot detect or create the spark needed to start the burner.

Your boiler is unable to move water around your heating system because the internal pump responsible for circulation has stopped working.

Your boiler’s internal computer has flagged a critical error while running its own health check, preventing the system from operating safely.

Your boiler has stopped working because the water pressure inside the heating system has dropped too low.
